MK 4 MOTOR CONTROL is a portable device that allows controlling 16A three-phase hoists. Each hoist has its own control with stop, normal turn and reverse. The hoists can be synchronized by dialing the direction of rotation and started from a single button. As protections, it has a 32 A tetrapolar circuit breaker and a bipolar circuit breaker to power the maneuver. In addition, the device incorporates indicators to show the presence of each phase. The emergency stop button is an added protection to stop all engines. The device is supplied in a heavy-duty ABS case with lid and handle.
